Question

previous l 14 of 14 l return to assignment Part B What is the wavelength of light that must be absorbed to accomplish this process? A 91.1 nm Submit My Answers Give Up Correct Significant Figures Feedback: Your answer 91.2 nm was either rounded differently or used a different number of significant figures than required for this part. Part C what will occur iflight with a shorter wavelength than that in part (b) is used to excite the hydrogen atom? light with a wavelength shorter than 91.1 nm is used to excite the H atom, the excess energy will become the kinetic energy of the ejected electron. if light with a shorter than 91.1 nm is used to excite the H atom, the excess energy wia be devided to the kinetic and potential energy of the ejected electron, lflight with a wavelength 91.1 nm is used to excite the H atom, the excess energy will become the potential energy of shorter than the ejected electron. lf light with a wavelength shorter tan g1.1 nm is used to excite the Hatom, there wil be not enough energy to eject an electron Submit My Answers Give Up kindle

Explanation / Answer

The frequency associated with the wavelength calculated in part (b) is analogous to v0 on the plot. (Threshold frequency)

Any excess kinetic energy imparted to the ejected electron corresponds to the sloped line to the right of v0
